HV19.H1 Hidden One

Sebastian

Sometimes, there are hidden flags. Got your first?

Challenge Description

Hidden One came out the same time as HV19.06 bacon and eggs came out, so I thought it might be about the extra information added below the bacon cipher ciphertext.

Born: January 22
Died: April 9
Mother: Lady Anne
Father: Sir Nicholas
Secrets: unknown

The extra tabs and spaces behind the facts looked interesting. So I googled for whitespace encryption which lead me to http://www.darkside.com.au/snow/. Downloading the tool and running it reveals the flag: HV19{1stHiddenFound}.
